Characterization of potato leaf starch.
Ní féidir ach le húsáideoirí cláraithe ailt a aistriú
Logáil Isteach / Cláraigh
The starch accumulation-degradation process as well as the structure of leaf starch are not completely understood. To study this, starch was isolated from potato leaves collected in the early morning and late afternoon in July and August, representing different starch accumulation rates. The starch
The effect of structural properties on rheological behaviour of starches in binary dimethyl sulfoxide-water solutions.

This research study analysed the rheological properties of potato amylose and potato amylopectin in binary solutions of the following water and dimethyl sulfoxide concentrations: 90% DMSO (1), 80% DMSO (2) and 50% DMSO (3), with preparation methodology involving the dissolution at the temperature of
Molecular characteristics of amylose and starch in dimethyl sulfoxide.

Logáil Isteach / Cláraigh
The aim of this work was the molecular characterization of starch polysaccharides to determine solution structure. Studies of amylose and potato starches of different origins were carried out by the static light scattering, dynamic light scattering, and HPSEC-MALLS methods. Molecular parameters such
Effects of different treatment methods on properties of potato starch-lauric acid complex and potato starch-based films.

Logáil Isteach / Cláraigh
The effects of different treatment methods on the physicochemical properties of potato starch (PS) and PS-based films were studied. The complexing indices of PS-lauric acid (LA) complexes followed the order: pullulanase debranching (PD) > ultrasound treatment (UT) > dimethyl sulfoxide heating (DSH)
Development and evaluation of methods for starch dissolution using asymmetrical flow field-flow fractionation. Part II: Dissolution of amylose.

Logáil Isteach / Cláraigh
In this paper, we investigate whether dissolution in water under autoclaving conditions (140 °C, 20 min) or in dimethyl sulfoxide, DMSO (100 °C, 1 h), is preferable for characterization of amylose. Two types of amylose, potato and maize, were dissolved either in water using an autoclave or in DMSO.

The main objective of this investigation was to evaluate different methods of storage for Microsporum canis based on materials and equipment that are readily available in developing countries. We tested 32 strains of M. canis at - 20 degrees C in potato dextrose agar (PDA) in its plain condition, or
11beta-Hydroxylation of Cortexolone (Reichstein Compound S) to Hydrocortisone by Curvularia lunata Entrapped in Photo-Cross-Linked Resin Gels.

Spores of Curvularia lunata were immobilized by entrapment with photo-cross-linkable resin prepolymers and incubated to form mycelium in potato dextrose broth containing cortexolone (Reichstein compound S) as an inducer of steroid 11beta-hydroxylase. In a buffer system containing 2.5% dimethyl

Antimutagenicity of the water extracts prepared from the storage roots of four varieties of sweetpotato with different flesh colors was investigated using Salmonella typhimurium TA 98. The extract from the whole roots of the purple-colored Ayamurasaki variety effectively decreased the reverse
Cryopreservation at -20 and -70 °C of Pleurotus ostreatus on Grains.

Logáil Isteach / Cláraigh
Alternative substrates for cryopreservation at -20 °C have been little explored for basidiomycetes and could bring new possibilities of lower cost cryopreservation. Nevertheless, freezing temperatures between -15 and -60 °C are very challenging because they frequently result in cryoinjuries. The
Preparation of starch and other carbon fractions from higher plant leaves for stable carbon isotope analysis.

Logáil Isteach / Cláraigh
The measurement of the carbon isotope composition of starch and cellulose still relies on chemical isolation of these water-insoluble plant constituents and subsequent elemental analysis by isotope ratio mass spectrometry (EA/IRMS) of the purified fractions, while delta(13)C values of

A method for simultaneous determination of residues of three herbicides containing nitrogen, propanil (3',4'-dichloropropionanilide), linuron and diphenamide, in agricultural commodites was established. The herbicides were extracted by acetone from samples, transferred into dichloromethane, then the

OBJECTIVE
To increase yield of starch conversion to large-ring cyclodextrins (LR-CDs) by amylomaltase from Corynebacterium glutamicum (CgAM).
RESULTS
In this work, LR-CDs produced from pea, tapioca, corn, potato, rice and glutinous-rice starch by the recombinant CgAM were analysed by
